As companies work toward developing alternative sources for a world with ever-increasing energy demands, energy minerals are moving to the forefront of the conversation. AAPG’s Energy Minerals Division finds itself in the spotlight these days for its work in prospecting alternative energy sources, such as geothermal and hydrates, for commercial use. “We’ve got good momentum right now with interest in alternative energy,” said Ursula Hammes, AAPG Member, EMD president and president at Hammes Energy and Consultants.

Our industry has been through a lot of changes since 2000, due in no small part to the explosive growth in unconventional oil and gas. Petroleum geologists have had to adapt to this change by learning new skills to keep abreast of the technological changes required to explore and develop unconventional oil and gas resources.

The Energy Minerals Division celebrated its 25th Anniversary in 2002. The Division emphasized to the AAPG membership that it was AAPG’s center of activity on energy minerals and unconventional energy resources. EMD originally focused primarily on coal, uranium, geothermal energy, oil shales and tar sands. However, its focus expanded and in 2002, EMD’s most active unconventional resource areas were coalbed methane, gas hydrates, and unconventional energy economics.

Groundwater resources are valuable resources, especially in arid climates such as in South Africa where in a dry year they may receive no rain at all. Welcome to an interview with Surina Esterhuyse, who speaks to us about the special challenges facing water scarce countries and her particular experience in South Africa.

In 2017, AAPG celebrated the 100th anniversary of its founding in Tulsa, Okla. This same year was also the 40th anniversary of the establishment the AAPG Energy Minerals Division. The EMD has evolved as an organization over the past 40 years to reflect the changes in the mix of resources fueling the world’s ever-increasing energy demand.

I am pleased to serve as president of the Energy Minerals Division for 2018-19. My main goals for this year are to provide frequent, easily accessible, relevant, high-quality technical content, and to improve our member engagement and communication with the regions, local societies and other geological associations.

The Energy Minerals Division was organized in 1977 as an international forum for those working in the exploration, development and production of energy sources other than conventional oil and natural gas. Our purpose then, as now, is to serve the AAPG by advancing the science, energy economics, technology and geology as it relates to energy resources other than conventional oil and gas.

Workshop
Naples, Italy
Wednesday, 22 June Thursday, 23 June 2022, 8:00 a.m.–5:00 p.m.

Modelling carbonate sequences and reservoirs has always been a challenging task. Carbonate rocks are generated and subsequently modified by a large variety of biological, physical and chemical processes that start at the time of deposition and end today. To unravel the geological evolution and history of carbonate sequences is fundamental not only for understanding their hydrocarbons potential but also for their role as potential reservoirs for renewable energy (geothermal) or geological gas storage (CO2 and hydrogen). Several science disciplines are often involved to fully understand the characteristics of carbonate rocks and old approaches and new technologies and tools are nowadays applied in these types of sequences. The objective of this meeting is to allow scientists and engineers working on carbonate rocks in academia and industry to share their most recent experience, work, approaches and use of innovative technologies to increase the understanding of the very complex world of carbonates.

VG Abstract

In 1991, Gulf Indonesia and its partners discovered South Sumatra Basin’s first major gas field at Dayung in the Corridor PSC. A key feature of this field is that most of the reserves are held within fractured basement rocks of pre-Tertiary age.

VG Abstract

Production from unconventional petroleum reservoirs includes petroleum from shale, coal, tight-sand and oil-sand. These reservoirs contain enormous quantities of oil and natural gas but pose a technology challenge to both geoscientists and engineers to produce economically on a commercial scale. These reservoirs store large volumes and are widely distributed at different stratigraphic levels and basin types, offering long-term potential for energy supply. Most of these reservoirs are low permeability and porosity that need enhancement with hydraulic fracture stimulation to maximize fluid drainage. Production from these reservoirs is increasing with continued advancement in geological characterization techniques and technology for well drilling, logging, and completion with drainage enhancement. Currently, Australia, Argentina, Canada, Egypt, USA, and Venezuela are producing natural gas from low permeability reservoirs: tight-sand, shale, and coal (CBM). Canada, Russia, USA, and Venezuela are producing heavy oil from oilsand. USA is leading the development of techniques for exploring, and technology for exploiting unconventional gas resources, which can help to develop potential gas-bearing shales of Thailand. The main focus is on source-reservoir-seal shale petroleum plays. In these tight rocks petroleum resides in the micro-pores as well as adsorbed on and in the organics. Shale has very low matrix permeability (nano-darcies) and has highly layered formations with differences in vertical and horizontal properties, vertically non-homogeneous and horizontally anisotropic with complicate natural fractures. Understanding the rocks is critical in selecting fluid drainage enhancement mechanisms; rock properties such as where shale is clay or silica rich, clay types and maturation , kerogen type and maturation, permeability, porosity, and saturation. Most of these plays require horizontal development with large numbers of wells that require an understanding of formation structure, setting and reservoir character and its lateral extension. The quality of shale-gas resources depend on thickness of net pay (>100 m), adequate porosity (>2%), high reservoir pressure (ideally overpressure), high thermal maturity (>1.5% Ro), high organic richness (>2% TOC), low in clay (<50%), high in brittle minerals (quartz, carbonates, feldspars), and favourable in-situ stress. During the past decade, unconventional shale and tight-sand gas plays have become an important supply of natural gas in the US, and now in shale oil as well. As a consequence, interest to assess and explore these plays is rapidly spreading worldwide. The high production potential of shale petroleum resources has contributed to a comparably favourable outlook for increased future petroleum supplies globally. Application of 2D and 3D seismic for defining reservoirs and micro seismic for monitoring fracturing, measuring rock properties downhole (borehole imaging) and in laboratory (mineralogy, porosity, permeability), horizontal drilling (downhole GPS), and hydraulic fracture stimulation (cross-linked gel, slick-water, nitrogen or nitrogen foam) is key in improving production from these huge resources with low productivity factors.
